Document Summary
Ionic- when difference is 1. 7 or greater, the bond is usually ionic. Covalent (nonpolar): the na-cl bond is ionic, the c-c (carbon-carbon) bond is covalent, the c-o (carbon-oxygen) bond is polar covalent, the o-h (oxygen-hydrogen) bond is polar covalent, the c-h (carbon-hydrogen) bond is covalent. Molecules which contain ionic bonds will be polar. Molecules which contain many polar covalent bonds will be polar, (with just a few exceptions) Molecules which contain many covalent bonds will be non-polar. (gave example of molecule of water and shows polar covalent bond between hydrogen atoms and the oxygen atom) Bonds which are not involved in making a compound. Weak attractions between atoms on different molecule or different parts of a large molecule. Occur between molecules that have polar covalent to ionic bonds. Compound- a substance consisting of two or more different atoms, in specific proportions, bonded together in a specific pattern.
